N2 - Underwater acoustic research nowadays is very much needed to achieve mastery of technology in underwater communication systems. At this stage, there isn't much literature on tropical seawater such as in Indonesia. To achieve these key technologies, it is necessary to master these supporting technologies. Instrumentation in communication systems using underwater acoustics signals must be calibrated through the preparation stage before being implemented in the ocean experiment. In this paper, underwater acoustic signals measurement results are compared to two different hydrophones with different sensitivities. The experiment was carried in the test tank of the Hydrodynamic Laboratory of BRIN, in order to investigate the performances of underwater acoustic instrumentation. Based on the test, it concluded that the hydrophone B, with sensitivity of -208dBV re 1μPa, has a higher sensitivity than another hydrophone A, with sensitivity of -180dB re 1V/μPa. This is proven by the ripple in the received signal from the hydrophone A. With the frequency variation in the transmitted sinusoidal signal, the hydrophone A has a negative correlation between the PSD and the frequency change with the value of 0,9947.
